SIGTUNA Bicycle Lock for Road and E‑Bikes

This sturdy U-lock combines heavy-duty materials with practical mounting for everyday cycling and secure storage of an e-bike or folding bike, making it straightforward to lock up while commuting or stopping for coffee. It works as a bicycle lock for e-bikes and folding bikes and aims to offer high resistance to cutting and leverage attacks while remaining easy to carry.

Key Points

The lock features a robust shackle made from hardened steel with a protective PVC coating to prevent frame damage and reduce noise when transporting. It includes a 1.2 metre cable that lets you secure the frame and one wheel to a fixed object, adding flexibility when fixed anchor points are awkward. The cylinder is a disk-style high-security type with a double locking mechanism that, according to the manufacturer, improves resistance to picking and prising attacks. 🚲

This model comes with three keys, so you can carry one on rides and keep spares at home. A practical bracket is supplied for frame mounting and a Velcro strap helps keep the lock tidy when not in use. Consider that, as with most U-locks, extremely determined attacks with heavy power tools may still be possible, so use the cable and lock together when you can for extra deterrence.

Usage Recommendations

Attach the bracket to your bike frame using the supplied fittings to keep the lock accessible on the move. When stopping, loop the 1.2 metre cable through the wheel and frame and secure both with the U-shackle to a fixed post or railing, to reduce the chance of wheel removal or levering attacks. For short urban stops the lock alone is often suitable, while longer or higher-risk stops benefit from using the cable and U-lock together. 🔐

If you plan to leave the bike overnight in an isolated area, try to choose well-lit, busy locations and lock to a sturdy anchor point. The lock stores neatly on the bracket and the PVC cover helps avoid scratches to the paintwork when carried. Keep one spare key in a safe place because if all keys are lost the manufacturer may require proof of purchase for replacements. ⚙️
